Abstract

BIOSYNTHESIS OF GOLD NANOPARTICLES USING PIPER NIGURM SEED EXTRACT AND THEIR ANTIBACTERIAL ACTIVITY

R. Devika, S. Elumalai

Abstract

A novel environmentally benign bioprocess of gold nanoparticles (Au-NPs) have developed using Piper nigrum seed extract. The bio reduction of Au+ ions in solution was monitored using UV-visible spectroscopy from zero reading and double distilled water was used as blank. The samples was measured at various time intervals and the absorbance were noted. The gold nanoparticles synthesized using seed extracts of samples was confirmed by color changes and was characterized by UV-visible spectrophotometer. The UV-visible spectra showed a broad peak located at 540 nm for gold nanoparticles. The Scanning Electron Microscopy (SEM) analysis shows the surface morphology of Au-NPs. Therefore these gold nanoparticles are potential as antimicrobial compound against infectious pathogens.

Keywords: Gold nanoparticles, Piper nigrum, Antimicrobial Activity and Spectroscopic studies.
